| Summary: | The article describes a power source designed for arcjet thrusters
of corrective propulsion systems of small spacecraft. The source
is galvanically isolated and provides high energy efficiency at
a consistent load. The design contains a push-pull converter
with a midpoint, which is covered by the feedback circuit for
the output current. The inductance connected in series in the
circuit smoothes the current pulsations generated by a pulsewidth modulator. The absence of a storage capacitor in the output
circuit allowed for a quick response to adjust the pulse width in
accordance with changes in load resistance. The results of the
experiments confirmed the theoretical calculation and simulation.
In the current stabilization mode, the source output power is 40–
120 W with an input voltage of 12–18V. |
